PIXMA MG6821 won't scan - prints okay but has trouble recognizing new cartridges

[REM071947]

My Pixma 6821 uses the 270 / 271 series ink cartridges.

I have error code 1413. The cartridge is a NEW Canon wider black ink cartridge.

Is there another way to address this issue.

Cartridges are expensive to have bought & then not be able to use!

A tech at Best Buy, where I got it and went to get a new black 270 cartridge today

said "take a clean cloth and rub the contacts where the cartridge is inserted

as some dust or grit there may interefere with the connection." I tried this several

times but it still won't 'recognize' the new black 270 cartridge!

contact me at [Removed personal information per forum guidelines], please.
